Abstract:
〈 i 〉 Background/Objective: 〈 /i 〉 The prevalence of sleep-related complaints (SRC) and the frequency of sleep-disordered breathing (SDB) in obese patients has not been studied extensively. We investigated SRC and SDB in a group of obese persons as part of a preoperative workup for weight reduction (bariatric) surgery. 〈 i 〉 Methods: 〈 /i 〉 All consecutive patients attending a weight-loss clinic for evaluation for bariatric surgery were asked to complete a questionnaire. The questionnaire consisted of a section on SRC and a validated general sleep questionnaire (Sleep Wake Experience List). The patients underwent sleep studies in which an Edentrace recorder registered heart rate, chest wall movements by impedance, airflow and oxygen saturation. 〈 i 〉 Results: 〈 /i 〉 Fifty-one patients (14 men, 37 women) were evaluated. Mean body mass index (BMI) was 45 kg/m 〈 sup 〉 2 〈 /sup 〉 (range 33–61). Eighteen patients (35%) demonstrated SDB, defined as (a) an apnea/hypopnea index ≥5, and/or (b) more than 2% of registration time with an oxygen saturation below 90%. There was no difference between these 18 patients and patients who did not exhibit SDB in age, sex, BMI or SRC. Seven patients had SDB of a severity warranting closer investigation and perioperative monitoring. 〈 i 〉 Conclusion: 〈 /i 〉 Both SRC and SDB are common in obese patients. Limited nocturnal respiratory monitoring is indicated as part of the preoperative workup for weight reduction surgery.
